Studysummary This study found significant differences in bcl-2 expression between areas of the scalp affected and unaffected by androgenetic alopecia, suggesting a uniform follicle population or synchronized follicular cycling in affected areas.

This document is a compilation of four different studies investigating the role of apoptosis (cell death) in androgenetic alopecia (AGA). The studies analyzed scalp biopsies from male cadavers with AGA and found differences in bcl-2 expression between affected and unaffected areas of the scalp, as well as differences in bcl-2 staining indices between frontal and occipital follicles. The studies suggest that apoptosis plays a role in the development of AGA, but further research is needed to fully understand the mechanism.
